Abstract:
The H. E. S. S. (High Energy Stereoscopic System) Galactic plane survey (HGPS) was performed with the H. E. S. S. I Cherenkov telescope array in Namibia from 2004 to 2013. In total +/- 2700 hours of high-quality observations of the Galactic plane are available in the Galactic longitude range of 250. to 65. and Galactic latitude range of -3.5 degrees < b < 3.5 degrees. This is the first high-resolution (0.1 degrees) and sensitive (1.5% Crab nebula point-source sensitivity) survey of the Milky Way in TeV gamma-rays. The HGPS has revealed a diverse population of cosmic accelerators in the Galaxy, from which we have compiled a catalog of 78 very-high-energy (E > 0.1 TeV) gamma-ray sources. In this contribution, we will show the latest survey maps, describe the source catalog construction method and further results from the upcoming HGPS paper such as source population statistics and the association of H. E. S. S. sources with known pulsar wind nebulae and highly energetic pulsars, supernova remnants, binary systems and GeV sources detected by the Fermi-LAT.
